dc.description.abstractBackgroundSkin cancer incidence among young adults is rising; however, the epidemiological characteristics of primary cutaneous lymphomas and cutaneous soft tissue sarcomas (CSTS) in individuals <30 years old has not been investigated. We analyzed the incidence and time-trends of primary cutaneous malignancies in children and adolescents/young adults (AYA).ProcedureSEER-17 and -13 data were used to assess the descriptive epidemiology and time-trends in incidence of primary cutaneous malignancies in children and AYA. SEERStat and Joinpoint softwares were utilized to estimate annual percent changes (APC) in incidence.ResultsIn total, 7,814 cases (ASR=25.66/1,000,000 habitants) of primary skin cancers in <30 years old were diagnosed in 2000-2008. Females had a higher incidence of melanoma (risk ratio (RR)=1.95; P<0.001) and a lower risk of developing CSTS (RR=0.64, P<0.001). Compared to whites, blacks have a lower incidence of melanoma (RR=0.03, P<0.001), and higher risk of CSTS (RR=2.28, P<0.001). Melanoma increased in females over a 15-year period (1992-2006) (APC=2.5, 95%CI=1.8; 3.2), and the incidence of cutaneous T-cell lymphomas increased over the period 1992-2008 (APC=9.5, 95% CI=6.7; 12.4). CSTS incidence decreased among males over the period 1992-1999 (APC=-21.4, 95% CI -27.2; -15.1), particularly due to a decrease in Kaposi sarcoma incidence (AAPC 1992-2008=-13.6, 95% CI=-22.4;-3.8), although with a notable racial disparity (whites, AAPC=-15.2, 95% CI=-23.2;-6.4; blacks, AAPC=-10.6, 95% CI=-13.2;-7.9).ConclusionsNon-melanoma skin cancer is very rare in children and AYA. We have shown variation in time-trends in incidence as well as in incidence patterns by race, sex, age, and histologic type, highlighting the importance of descriptive epidemiology to better understand the characteristics of these malignancies.
